Justin Bieber and Selena Gomez have broken up after dating for over a year and a half. It’s over. The split to end all celebrity gossip splits took place last week.

Selena, apparently, was the one who ended it.

Says a source close to the cute, former couple:

“She broke up with him about a week ago. With them being apart so much it got complicated. She had some trust issues. It’s not easy, but the relationship needed to end.”

It’s unclear what “trust issues” those were, or if their breakup, which was first reported by E! News, was prompted by anything more than the strain of long distance.

Selena, 20, and Justin, 18, went public in February 2011.

They fought off breakup rumors on numerous occasions since then but seemed relatively stable, frequently going on dates and looking very happy together.

And there you have it.

Justin, however, doesn’t seem to be too down and out over the breakup, as he was spotted gettin’ his flirt on with a handful of bangin bawwdied Victoria’s Secret models before and after his performance at the VS fashion show taping earlier this week.
